My invention relates to valve mechanisms.

An object of my invention is to provide an improved valve mechanism.'Another object ot my invention is to provide an improved 'valvemechanism especially `adapted to u se with pumps,compressors `or thelike. Still another object ot my inventlon is to provide an improved.valve mechanism oit compact, rugged, and simplecliaracter having an improved arrangement of the lvalve springs and other component parts.rlhese. and `other objects and advantages will hereinafter more In theaccompanying dravvlngs I have shown for purposes of illustration oneform which my invention may assume in. practice.

Fig. l is a plan view ofiny improved valve mechanism, parts beingbrokenaway to facilitate illustration.

substantially online Elf-2 of liig. Fig. El is a detailperspective vievvof my improved valve spring shown in position on thefvalvea i y ,i ,W vr In the illustrative iorinof myl invention I r have shown a valvemechanism of improved lili Jform enerall designated- 1, comprising aseat Tiiegmber 2 :ind a guard member 3. llerein, the seat member 2 `isprovided with a central recess 4in which an annular` depending portion 5on the guard member regrsters, the `seat and guard being rigidly held in"asf sembled relation by means of a bolt Sand a lock `nut 7 disposedWithin a recess" 8 in the bottom of the seat. `As illustrated, the seatE2 is provided with a plurality ot annular, con`- centrically disposed,ribbed flow openings 9 and 1U vvhich are closed by annular p ate valvesIl and l2 movablerelative tothe guard 3; These `valves are normally heldseatedlby means of a plurality of radially disposed leatl springs `i3having bowed central portions lll and flattened or slightly curved endportions 15.` Herein, thesesprings 'are disposed in chambers `16 oimedinrectangular shaped members 17 formed integral Withthe guard 3; It Willbe observed that the guard is pro`` vided with depending valveq guidingportions 18 and 19 adaptedjto guide the valve ,l1 and curved guidingportions 2O formed on `the depending portion adapted to guide the valvel2, The guides 19 likewise prevent lateral `displacement of the valvesprings 13. Herein, spacedannular ribs or backing mem bers 21aiid Q2formed integral With the guard member backup the valves 11, 12 in theirraised position. The depending portion `5 of the guard is cut away lormilled as at 2?),to permit a free flow of the compressed fluid. r

As a result of my improvement it Willbe n oted thata valve mechanism ofexceedingly simple, compact, and rugged character is produced `havingimproved valve springs, large flow ports, 4and arrangement of other comLponent parts which may be manufactured with facility and ata minimumexpense.` It Will further be noted that single valve springs arranged atdifferent radial points are used for seating both valves and that theguidesfor the valves alsovsei've as i lateral displacement of the valvesprings.

y While I have in this application specifically described one forni4vvhich my invention may assume in practice, it will be understood thatguides for preventing (ifi this form oi.' the same is shown for`purposes of illustration and thatytheinvention may be modified andembodied in variousfother forms Without departing from its spirit or thescope of the appended claims.
